First off - I agree with a negative review in part - you'll want the blue envelopes over the yellow
envelopes since you might be able to see in the yellows (I haven't seen that trick but makes sense).
I have the blue version and it works great.
It's a hair pricey - but you're paying
to reward a smart magician for their innovation and also to get a mind baffling trick into your show
that you can do over and over.
At one point the instructions mention something about using
a cheap soft glue - I would only say that I'm a hobbyist not a pro and I've done this without using
that at all. With just a hair's worth of attention to detail and relatively little slight of hand I
don't think you need any sort of glue - so you might want to try it that way first.
It's a
smart trick - if you're creative you can add to it - if not - just watch the video above for the way
to present it.
As the envelopes arrive blank - you can write whatever you want on them -
which right out of the box puts you in a creative state. Or again - you can watch the video and the
trick exactly as he did.
Either way - you'll wow small groups and large alike - so - watch
the video and believe the hype. This is an easy trick that packs a heck of a punch.
